His 31- lhc iiiiiei' nice thereof. in

outer xm-iiun in form an air space "50 thni when 1hr latter is l" lugsFf sh ps .i min carried alon in an upward direction. In order to holdthe inner boards D, D spaced apart while filling concrete materialbetween the corresponding boards B, D and O, I), use is ma e of s acingplates K provided with heads'K' a apted to rest on the top edges of theboards D, D, and reaching with their terminals to the inner faces ofthel plates E, E and which plates practically clamp the heads K intransverse osition. The ower edges of the inner boarc s D, D areprovided with notches D to allow the insertion of binding keys L of anyapproved material, to unite the wall sections A and A with each other atsuitable intervals, as indicated in Fig. 1.

The boards or plates B and C are liable to warp, and in order to bringthe same into proper alinement use is made of angle irons or rails N,extendin along the lower ends of the boards B an C and secured to thelower ends of the reinforcing bars F (see Fig. 4). Thumb screws N screwin the angle irons or rails N against the outer faces boards C and D.After the'material hast of the boards B and C, to enable the operator tobring the boards B and G into a straight line position, thus insuringthe formation of straight walls The boards B and C as well as the platesE and E are connected at the corners of the wall sections A and A bysuitable fastening devices, such as apertured lugs O and removable keys0, as p ainly indicated in Fi s. 3, 8 and 9.

In case the inner boar not join properly atthe corners of the wallsections and A, then use is made of angle plates P (see Figs. 2 and 11)having lugs P at their u per ends for supporting the angle lates P romthe top edges of the boards D,

Joint plates Q are used on the adjacent ends of the boards B and C, asindicated to the left in Fig. '2, but other suitable means may beemployed for the purpose.

in order to provide a. facing A of a finer cementitious material thanthat,- used for building the main portions of the wall, use is made ofplates R (see Figs. 1 and 7), arranged spaced from the inner faceof thefacin board B, the lates R overlapping one t e other in the direction ofthe length of the mold, as indicated in Fig. 7. Each of the plates R isrovided at its top with an outwardly-extending flange B extending overthe to of the board B, and each flange is provide with an aperture R forthe insertion of a pin or a rod S extending downward between theopposite faces of the correspondin plate R and the board B, so that theplate K is spaced from the board B corresponding to the diameter of thepin S. Now in forming the outer wall section A the concrete or othereementitious material is; filled in between the board D and the platesR, and a like material is filled in between the s 1), n, n, n do,

loosen the plates Lt.

somewhat set the plates 11, and the pins S are removed and then thespace between the outer face of the wall section A and-the inner face ofthe facing board B is filled in with fine cementitious material, 'whichreadily adheres to and forms the facing A for the wall sectiou A, asplainly indicated in the lower portion of Fig. 1.

fter the outer and inner wall sections A and A have been lillcd to aboutthe height of the boards B. C, l) and D, then the mold is raised by theuse of the screw rods 1 and the foot boards J resting on top of the wallsections just finished. By having two screw rods I on each cross bar l1and turning the same sinuiltaneously, it is evident that the mold isproperly raised without danger of moving any of the boards in atransverse direction, that is, the boards are raised vertically untilthe lower endstof the boards 13, C, D, 1) contact with the upperportions of he wall sections A, A already built, as will be readilyunderstood by reference to Fig. 1. The keys L are set in positionimmediately previous to starting the next course for the wall sections Aand A, so that the keys are partly embedded at their ends in the twosucceeding courses.

From the foregoing, it will be seen that by the arrangement described,the wall can be readily built in sections spaced apart to form an airspace, the enter section can be provided with a facin of finer materialthan that forming the body of the wall, and the wall can be readilybuilt u in courses to any desired height by perio ically raising themold on the operator turning the screw rods 1, as above explained.

If desired, the inner face of the facing board B may be made in stepform, as indicated in Fig. 12, so as to give the outer face of the wallsection A a clapboard appearance, otherwise the construction of this isthe same as before described, except the the plates R and the pins S areomitted.

By providing the boards B and C with the rail N and adjusting screws N,all leakage of the concrete material and facing material is prevented,and by arranging the plates R and the ins S in the manner described,-theplates are firmly held in place while filling in the concrete materialfor the wall section A, and when this has been finished the pins S canbe readily pulled up, to and thereby allow their convenient withdrawalfor the subsequent filling of the facing material. It will also benoticed that by haviiw the rigid frame 1) locked to the upper cues ofthe reinforcing bars 15, the mold boards B and C are firmly held inposition, to insure the formation of perpendicular wall sections withoutrequiring adjustment of the parts of the mold.

The reinforcing bars F are prfgrably t t g t t t t l 10. A wall mold;comprising a facing board, a rear wall board, intermediate boards,spacing devices for the said intermediate hoards, vertical bars on thesaid facirig board and the said rear wall board and projecting beyondthe top thereof, the upper ends of the said vertical bars being providedwith inwardly extending hooks for the boards to swing outward, a topframe having plates connected with each other by cross bars. the topframe plates resting on the said facing board and the said rear wallboard, the cross bars having apertured lugs for engagement with the saidvertical bars, and keys for fastening the said lugs to the said verticaliriltS.

11. A wail mold having a mold board, vertical bars secured to the saidboard, a rail secured to the lower ends of said bars and extending alongthe lower end of the mold board, and screws screwing in the said railand abutting against the outer face of said board.

A wait mold having a facing board, a rear board, vertical oarssecured to the outer faces of said boards and extending beyond the topsthereof, rails secured to the lower ends of the said bars and extendingalong the lower ends of the boards, screws screwing in the said railsand abutting against the outer faces of said boards, a top frame restingon the said boards, and means for removably securing said frame to theextensions of said rertical bars.

13. A wail mold comprising 21 facing board, removable plates held spacedfrom the inner face of the facing board, a rear board, verticalreinforcing bars on the facing board and the rear board and projectingbeyond the tops thereof, a top frame having plates resting on the facingboard and the rear board, cross bars connecting the plates and havingapertured lugs for engagement with the said reinforcing ban, and meansfor removabiy securing the lugs to said reinforcing bars.
